(Figs. 1 and 11i. Tho driving allait issnpported in hearings in two plains l sown-od lo Itho benin 23 and, at `rho roar, in a hearing `at thoond of a A `pinion 36 is fixed on tho shaft .33 and Ain n'ieshovith a gear 37 serum-d to a shaft 38. Thegoar 37 engages driven in opposite directions, respectively, rby a straight and a-crossed beit. A friction wheel 46 is secured to the shaft 33 andA a rack 39 attached to the lower side of a slide 40 resting upon the upper side of the beam 23 and secured against displacement by an ovcrlaying plate 41. The slide 40 may be provided at its ends with Vrolls 42 (Fig. 2) supporting the slide above the beam 23 to reduce the friction therewith. The slide is connectcdavith thcicarriage by means voil a slotted arm 43 Which engages a roll 44 mounted on a depending lug which may be formed integral with the block 28.v

`It is apparent -from Figs. 1, 2, andll that rotation of the driving shaft 3 3 Will impart asliding motion to the heel block carriage.

As this 'machine is at present constructed,

it is desirable that a reciprocating motion shall be imparted to the heel block carria e. It is not' essential tol the spirit of the 1nvention, however', that the heel block shall reciprocate, the end to be obtained being to provide a traveling heel block andV this invention comprehends any other means of returning the block to its starting position.

ln order that the shaft 33 may be rotated alternately in opposite directions to reverse the direction of travel ofl the heel block carriage, a. pair of pulleys 45 (Figs. 1 and 11) are loosely mounted on the shaft and is driven in one directionor the other in accordance with which of thel pulleys it is engaged. The pulleys 45 may be moved longitlildinaliy of the shaft to engage either one with the friction Wheel 46, hy means of forked arms 47 which engage'at one end, the hubs of thekpulleys, and at the other, are secured to a slide rod 48. The end of theslide rod is provided with a spool which vis engaged by a ork'49, fixed on a vertical sliaft `50, the upper end of which is fixed to atinger 51. The slide 4G is provided with 4two adjustable abutments 52 and v53, one

of which engages the finger 51 as the slide approaches the end of its travel in either direction, rocks the shaft and, through the connections described, moves the pul- .leys 45 to disengage one andl engage the It will" other with the friction wheel 46.

I readily be seen from Fig. 1 that the abutment may' be located on the slide 40 in a positlon to stop and reverse the Vmotion of the heel block carriage when it is in 4that magazine.

front of any one of the series of lift niagazines 22. 1 v

An important feature of this invention resides in the lift delivering mechanism and in its manner of operation. The lift delivering mechanism of any one magazine is thrown into operation when the heel block is in litt receiving position with respect to The means employed to that end are best illustrated in Figs. 4, 5, 6,

.and 10, and as each magazine is provided tion, with a pin 59 at one end of slot 60, by a spring 6l. The slide is actuated at the proper-time by interlocking with a constantly reciprocating slide 62. This slide is connected, through a standard 63, alink 64. and a lever G5 movable 'about a fixed pivot 66, With an/eccentric strap G7. The eccentric strap embraces an eccentric G8 fast on a'sha't (59 having bearings in the end pieces 20 and which may be rotated by the pulley and a. belt 71. Power is ap-v 'I plied to the belt by a pulley on 'a shaft. 72 which, durin the operation of the machine, is constantly riven from any suitable source of powerconnected with the tigl'it pulley of a pair of pulleys 73. I

The slide 58 may be driven in one direc tion by the slide 62 by means oi' a latch 74 pivotally Inountcdon the standard (i3 'and normally held in a substantially horizontal position, as shown in dotted .lines in Fig. 6, I by a spring 75. 1While in this position the'` latch reciprocatcs with the slide G2 in a plane above a catch 7 6 mounted on the slide 58.` It' the latch is turned about its ivot to the full line position While the slice 624 is in the position shown in Fig. 5, one end` of the latch fisengaged 4byhthe catch 76 which must then move with e latch, therebyvcarrying the slide'dforward and delivering the lowermost lift in the magazine through thefopening 5G.

The latch 74 is turned into its operative position to cause a litt to be' delivered to the carriage by a trip lever 77 pivoted below the table '21 at 78, (Figs. 4 and 4The rear end of the trip lever has an npvvardly'projecting portion which contains a spring pressed plunger 7) adapted to engage a pin 80 in one end of the latch 74. The forward end of the trip lever has fixed therein a rod 81 thel lower end of which is engaged, at times, by a cam block 82. Tho cam block 82 is secured to the slide 40 in such relationto the heel block 24 that the triplever 77 is operatedV at the time the i heel block is 'opposite Vthe-magazine controlled by that trip.

As the slide 40 and the carriage have a reciprocating lmotion, as has been described, it is desirable that the trip lever 77 should be actuatedfwhen the carriage is traveling in one direction only, that is, a lift should he delivered to the heel block on its workvided to approximately determine the relation of each lift with the prevlousllift delivered to the heel block. The guides are adjustable to accommodate heels of varying i tary heel, to as great an angle as may be desired on ladies high heels, by adjusting a v Screw 127 in an upright 128 projecting from the bar' 125. A spring 129 holds the guide against the screw as is most clearly shown in Fig. 8. Two guides 130 are provided for the sides of the heel. These guides are pivotally connected with two arms 131 loosely secured to the block 24 by screws 132. Adjusting screws133, carried by uprights 134 -fixed to the arms 131, are employed to vary the angle of the`guides 130 in the same man- .ner as has been described in connection with the guide 124. The guides, as will be apparent, define a heelshaped space 'or recess and, with theblock, constitute a heel form to which the lifts are delivered, and in which they are assembled in the shape of a heel. When it is desired to change the side 130 is such that there is a slight clearanceV guides to accommodate a wider or narrower heel, the arms 131 are turned aboutV the.

screws 132 by means of screws 135 carried in straps 136 fixed to the heel block. Springs 137 extending from the straps 136 to projections on the arms, lholdthe` arms separated and against the screws 135.

The normal adj ustmentof the side guides on each side of a centrally positioned lift, thus allowing the possibility of irregularity in' the vertical outline of the heel.v The lifts are correctly positioned, or the heel is trued up, by pressure of the guides 'upon` the sides of the heel and the pressure'atl the back and at the breast ofthe heel," between theguide 124 and the plate 121. The side guides are forced toward each other and against theheel during the last part `of the sliding movement of the heel block 24 un der the impulse of the lever 111. The ends of the arms 131 are beveled at 138 (Fig. 4) to afford a cam action when the beveled portions enpiageV two screws 139 threaded into straps 140 secured to the bend piece 20. The sliding movement of the heel block also presses the heel against the breast plate 121 by the force of the guide 124 at the back of thel heel. The manner in which the heel in truedupisbest illustrated'in' Fig. 2 and Fig. 8 in which the heel support 110 and the breast plate 1,21 are shown in heel rev 4 ing driven.

ing in a bracket 147 secured to the end piece heel having a curved taper, such, for in stance, as a Louis heel.

It is desirable that the lifts should be se- .curely fastened together before the heel is ejected from the machineand this is preferably accomplished by driving a nail through the heel. As illustrated in Fig. 1,

a raceway 142, which may be of any suitable form, provides nails, from any convenient source of supply, to a driver 143. The driver is adjustably mounted in a slide block 144 which is carried in a continuation of the slot 119, to which reference has been made. (See Fig. 7.) A foot 145 carried on the lower end of a spring supported plunger 146 is provided to clamp the heel upon the heel support 110 while the nail is be- Theplunger 146 has a bear- 20 and it is thrust downward upon the heel by a bar 148 carried in a way in the slide block 144 and held yieldingly downward by Va heavy spring 149. The slide block 144 is joined by a connecting rod 150 with' an eccentrically mounted pin 151` in a disk 152 having a .bearing in the end piece 20. The disk 152 is rotatable with the driven member of a clutch 153 which also carries a cam 154' to actuate the lever 111 which has been described.

The clutch 153 is driven by the shaft 72 and may be of any of the well known forms for turning the driven member through one revolution, but,"for. tl1e purpose of illustration, it has been shown as having a plunger 155 which is engaged with the driven member by the movement of the lever 156.

The clutch is rendered operative by the heel block carriage lasit reaches the end of its travel toward the heeldelivering end of the machine, that/is, to the right in Fig. 10. As the sl/idel 40 comes to this position, a stud 157, carried on a strap 158 secured to the slide, contacts with the upper end of a lever Lit/9, the lower end of which (see Fig. l) isconnected by a link 160 with the 1ever 156. By this construction the clutch 153 is rendered operative to slide the heel block 24 on the block 25 and,- by proper timing of Vthe cam 154, then to drive the nail. The lever 111, being at once retracted by a spring 161, allows the heel block to return to its normal position under the stress of the springl, leaving the completed heel on machine.

The ejeeting devices, as at present ernployed, comprise a rod 162 (Fig. 7,) adjustably secured to a lever 163 pivoted on the end pierce 20. 'llie lower end of the lever is held to the left, under the impulse of a spring 1(5-1, so far as it is permitted. to go by a latch 1Go which engages the up', er end of. the lever. A rod 166 connects one end of the latch with a lever 167 (Fig. 10) pivoted at 168 on the beam 23. The other end of this lever carries a trip 169 which is free to swing in one direction but is stopped in the other direction by a pin 170.` '[he stud 157, hereinbefore described, has an eX'- tending end 171 of reduced diameter.

' thel slide Ll0, and. perfor-ee, the heel bleek earl-lage, travels to the right in Fig. 1U, the trip 169 swings to allow the pin 171 to pass, but on, the return oi' the pin the angular lower surface of the trip causes the end of; the lever T to rise thereby pulling down the rod 166 and releasing the upper end of the lever-1153 from the latch 165. The lower end of the lever then swings sharply to the If-lt by the action of the spring 161 and. the rod 1132 strikes 'the heel and throws it from the machine.

'lhe ejector is reset by the Continued movement of the slide et() on its idle o' return stroke. rlfhe lower end of the ,lever 163 is eouneeted by a link 172 with a post 173 rising 'from the end oi a earn lever 171 mounted on a lin-:reitet on the front of the been The slide 4l) barrios a' depending 175 which engages theo-ain end of the bor-rr 174: and therel swings the lever 163 lo its, original position Where it is retained by the .latch 165 'until another heel is to be ejected. Fig. shows the lever 171 in dotted lines in the position it occupies directly after the heel has been ejected and in full lines in the position. to which it is returnedby the lug 1?'5 in. its travel to the right.

.ln order that the manner and facility oi adapting this machine to building heeiset a different size, height, and shape may be elearly understood, it will new be assumed that it desired to adios` the machine to build heele of only lits, that is, Wh.

is known as a heel. The first operation is to throw the drivingr pulleys into neutral position, by niean's of a'handle 176 aft-e which the heel block Carriage may be moved by lthe hand wheel 177. The hand Wheel is nbw turned to bring the heel bloei; 2% into line with the fifth liftlmagazine,'oounlmg from the left in Fig. 1. The abutment is moved to a position in Contact bwith the finta-r 51 and the earn plate 88 (F 1g. 10) is moved into engagement with the stud These "'V'Iiusimn-nts will, when the machine is' started, cause the o'vfn block 89 to be lifted into the plane of the rods 81 and the carriage to reverse its direction of travel. at the proper time. The surface of the heel block 9x1 is now foundto be belenr the level of the bottom lift in the magazine in juxtaposition thereto, so the jack 3l fis manipulated to raise the upper end of the way 2,9 until the surface of the heel bloek is but very slightly below the table 21. This adjustinent Will, however, have produced 'an error in the relation of the heel bleek and the lift in the last magazine tothe left when the block is in receiving position thereto. This is corrected. by adjusting the screw 30. The guides 130 and the guide 1211 are now adjusted to Correspond to the shape and size of the heel to be built, in a manner which is plain from the foregoing description. The heel support 110 is adjusted by the screw 120 to bring its level slightly above that of the heel blootr at the end of its working stroke and suela minor adjustments may be necessary are made to the nail driver and the ejector. The pasting arrn 89 (Fig. 5) for the fth magazine is then removed and the machine is ready tooperate.

In the operation of this machine, the heel block 24 starts its working stroke from a point slightly to the right of the first magazine from which a 4lift is to be taken which, as is illustrated in Fig. 1, would be the sixth magazine. As the earn block S2 engages the first rod 81, a -lift is delivered to the heel bleek, as has been described. Lifts are delivered from successive magazines in the saline Way. l't will be observed that, as the Carriage travels, theA gradually increasing distance from the top of the heel bloeitl to the level of the table 21 Will compensate for the inrrease in the height of the heel being built so that the top of the partly vformed heel is always at the right height to receive the nextlift. The pasting arms 89 Which are continuously operating, will-keep the: bottom lift in-eaeh magazine, except the sixth, which will be the bottom lift 'ont-he heel bloeit, Well supplied with fresh paste.

After passing the series of magazines, the

heel bleek is turned the rack 106 and th.,I

gear segment 105, the eluteh 153 is throwninto operation and the Cain block 82 is depressed. The heel bleek 24 then slides for rrd by reason of the lever 111 .and delivers the heel i; the heel support at the same time trning up the Vheel by thepressui'e of the plate on the heel breast and guides at the sides and back. `The heel block carriage' at once starts to return, its direc-tion of travel being reversed by. the' abutment 53 engaging the fingerl; The heel is nailed and ejected during the first part of the rev turn stroke of the carriage, thezejector reset, as has been deseribeiandfinally thev cam block SQ-iselevated, the abutment 52 aetnates the finger 51 and the carriage starts another working stroke.

lilo

` ducing heels of a standard shape and size and then trimming the heel to one of'several finished forms, the contour of the rough heel can be easily varied so as to produce a rough heel for each of the finished forms, on which the minimum amount of trimming is required. i,

It is. to be distinctly understood that, While this invention haslbeen illustrated and described in the best form at prescnt'knovvn t the inventor, the construction and ai rangement of parts herein set forth is not essential t0 the invention and the true scope Voit' the invention is not limited thereby, except in so far as it is speciied and definitely set` forth in the claims.'
